DMWBAB BITCH Foa 'rAcToRs Application filed November 28, 1927. SerialNo. 236,256.

This invention relates to a draw-bar hitch' for tractors, and has forits .object the construction 4of a simple and efficient device whereby,machines can be attached to a tractor.

Another object of the invention is the construction of an attachingdevice, which is normally fastened to the gear housing of a tractor, andwhich will prevent the tractor from upsetting backwards.

A still further object of the invention is the construction of anattaching device" or hitch device, whereby the hitch l*is regulated onthe main bar several inches from either side of a' central point,without mov ing an of the machinery at any time.

Wit the foregoing and other objects in view, my invention comprisescertain novel constructions, combinations and arrangements of parts aswill be hereinafter fully described, illustrated in the accompanyingdrawings, and more particularly pointed out in the appended claim.

In the drawings:

Figure 1 is a view in side elevation of my device, showing the sameattached to a gear housing of a tractor, while Figure 2 is a top planview of the same.

Figure 3 is a longitudinal central sectional view of my device, whileFigure 4 is a perspective view of the same'.

Referring to the drawings by numerals, 1 designates the U-shaped frame,which is provided with a plurality of large apertures 2. Secured nearthe inner ends is a transverse plate 3 against the bottom of which isplaced a filler element or block 4, for the purpose hereinafterdescribed.

A pair ofhorizontal bottom braces 5 are fastened at their outer ends bybolts 6 against the under face of frame 1, and their inner ends arespaced and fastened against block 4 by bolts 7. A swinging hitch bar 8iS provlded near its inner end with a large slot 9, through whichextends bolt 10. This slot 9 is provided for making the adjustment ofbar 8 easy upon the frame 1. The outer end of the swinging hitch bar 8is formed into a loop 11 that surrounds the apertured end of frame 1.The loop 11 is provided with registering apertures 12, which alsoregister with the apertures 2 in frame 1. A suitable bolt 13 is placedin the apertures 12 and 2 to hold the hitch bar in different adjustedpositions upon the frame 1, as shown in full lines, Figs. 2 and 4' andfby dotted lines Bin Fig. 2. The bolt 10 is placed between bolts 7;consequently, the hitch bar 8 is pivotally mounted at its inner endbetween the inner ends of braces 5. The filler block 4 serves toyproperly position the inner ends of vbraces 5V and bar'8. l

To mount the frame 1 securely upon lthe gear housing 14, I provide twoprimary gearhousing connecting brace bars 15; thesebars 15 are inclined,and are provided with fiat feet 16 that'rest fiat upon the top ofv frame1, and throu h which feet extends boltl 6; the upper en s of bars 15 arefiat, as at 16', and these ends 16 are positioned in a ver-v ticalplane, so as to bear fiat against the vertical side faces of gearhousing 14. Through these fiat ends 16 extend bolts 17 of the gearhousing 14.

Auxiliary gearhousing connecting bars 18 are provided; these bars arepositioned horizontally and bear flat against the under face of frame 1,at their inner ends, with bolts 19 fastening said bars 18 to the frame.The outer ends 20 of said bars 18, are bent into a vertical plane, so asto `bear flat against the vertical side faces of the gear housing 14.Bolts 20 extend through the side faces of the ear housing and throu hthe dat ends 20 o1g bars 18, whereby these ars are securely fastened tosaid gear housing.

My device is a very rigid structure, so that if the tractor starts toupset backwards, as shown by dotted lines A Figure 1, the device willhit the groun and thereby prevent said tractor from upsetting. However,the adjustment of the swinging hitch bar 8 can easily be accomplishedupon frame 1, to obtain the desired hitch for vthe machine that is to beattached to the tractor.

It can be said that the hitch bar 8 has a swinging radius of twelveinches on either side of the central hole or aperture in frame 1. Theaccurate attaching or hitching of a machine to the tractor can thus bereadily accomplished without moving any of the machinery.

My hitching device is particularly adapted for the tractor known asFordson, and by the use of my device, a great many machines can bequickly attached to the tractor. This attaching may be through themedium of the ring or link 21 to which an ordinary clevis may besecured.

While I have described the preferred em- PATENTF OFFICE.

bodiment of my invention and illustrated the same in the accompanyingdrawings, certain minor changes or alteratlons may appear to one skilledin the art to which this invention relates, and I, therefore, reservethe right to make such chan es or alterations as shall fairly fallwithin tIie scope of the appended claim. l

What I claim is:

In a device of the class described, the coinbination of a U-shapehorizontal frameproa vided with a plurality of Vertical, large aperturesin its outer end, a horizontal transverse late secured at its ends tothe top of said -shape frame, a filler block between A the sides of saidframe and secured to the under face of said transverse plate, horizontalbraces secured at their outer endsagainst the under face of said U-shapeframe and at their inner ends to the under face of said ller block, aswinging hitch bar provided with a large slot at its' inner end saidslotted end of the hitch bar positione a ainst the under face of saidfiller block, a olt extending through said slot, filler block andtransverse plate securing said parts together, said hitch bar loopedaround the outer apertured end of said U-shape frame, said looped endprovided with registering apertures, said registering aperturesregistering also with the apertures 1n said U-shape frame, a pair ofinclined gear-housing brace bars provided at their inner ends with flatfeet secured against the upper face of said GEORGE sTARKs.
